Deletion of Vehicle Alert History

As the D/C cut fuse is removed, the communication between the various ECUs is interrupted.
When the D/C fuse is reinstalled, the communication status is restored, but Lexus Enform
Service Connect may store malfunction history in the form of vehicle alert history.
Therefore, it is necessary to operate the multi-display and delete the vehicle alert history AFTER
installing the D/C cut fuse during PDS at the dealership.
Deletion Procedure

1. Turn the engine switch (power switch) to the ON position (ON mode).
2. Push the Menu switch on the remote touch device.
3. On the multi-display, enter the following menus: Info – Vehicle Alert History.
4. If there is vehicle alert history stored, perform the Delete History operation.
HINT
If there is no vehicle alert history stored, the system will display a message stating
“There is no vehicle alert history.”

5. When the vehicle alert history deletion confirmation screen is displayed, select Yes.
HINT
If there is no vehicle alert history stored, the system will display a message stating
“There is no vehicle alert history.”

6. Turn the engine switch (power switch) to the OFF position (OFF mode).

Tire Pressure Warning System (TPWS) Initialization

Refer to the applicable Repair Manual for the TPWS initialization procedure.
Note the spare tire does NOT have a TPWS sensor.
NOTE
To adjust the tire pressure correctly when the outside temperature is significantly colder than shop
temperature, perform a Health Check using Techstream and select the compensation tire pressure
checkbox. Compensation pressures will display on the Health Check results screen. Adjust the tire
pressure when the tires are cold.

Parking Assist Monitor Initialization

As a result of the removal of the D/C cut fuse, the power source to the steering angle sensor is
cut off. When the D/C cut fuse is reinstalled, the parking assist monitor system/panoramic view
monitor will be operative, but it cannot display guidelines to assist parking operation because the
center position recognized by the steering angle sensor may not be in an initial position.
Therefore, perform parking assist monitor initialization AFTER installing the D/C cut fuse
during PDS.
Refer to the applicable Repair Manual for the parking assist monitor initialization procedure.

Steering Sensor Zero Point Calibration

As a result of the removal of the D/C cut fuse, the steering angle sensor power source is cut off.
When the D/C cut fuse is reinstalled, the center position recognized by the steering angle sensor
may not be the appropriate position. Therefore, it is necessary to perform the steering sensor
zero point calibration AFTER installing the D/C cut fuse during PDS.
Refer to the applicable Repair Manual for the steering sensor zero point calibration procedure.
